SWITCH.

Application filed September 15, 1917. Serial No. 191,622.

my co-pending application No. 166,250, and

the objects of the invention are to facilitate operating a track switch from the approachmg car or train, so that the desired path of travel may be taken without stopping the car or train to manually change the switch;

to simplify the construction of the switch actuating mechanism on the car and render it capable of being used on cars at present in use, and generally to adapt the several parts to better perform the functions required of them.

With the above and other objects in view, the invention consists essentially of the improved construction particularly described and set forth in the following specification and accompanying drawings forming part of the same.

In the drawings:

Figure 1 is a fragmentary sectional elevation of a railway track and car showing the switch actuating mechanism mounted thereon.

Fig. 2,. is a vertical section of the depressible plunger designed to actuate the track mechanism.

Fi 3 is an elevation of the same.

Lifie characters of reference refer to like parts in the several figures.

Referring to the drawings, A represents a railway track, and B a car, the said track being provided with a switch mechanism 0 designed to be actuated by the car mechanism D in the manner to be made clear hereafter.

The track mechanism consists of a crank shaft 10, which is adapted to actuate the switch in the manner disclosed in m copending application No. 166,250, being provided in one end with a gear 11 adapted to mesh with the gear 12 carried by the vertical spindle 13 which is provided in the upper end with a star wheel 14;. As the star wheel is rotated in a horizontal plane, the shaft 10 is rotated, and the crank of the said shaft actuates the switch. It is not thought necessary to further describe this part of the de vice, as it does not form a part of the present invention.

The car mechanism B comprises a standard 15 mounted on the deck 16 of the car, and provided with a slot17 in the lower end, and having an upper bifurcated end 18. Slidably mounted in this standard A is a plunver 19 provided intermediate of its length with a foot pedal 20, which slidably engages with the slot 17 and projects therethrough, so that the motorman or driver may depress the plunger 19 by exerting pressure on the foot pedal.

This plunger is also designed to belhand actuated and to this end I provide a cam 21 pivotally mounted on the bifurcated end 18 of the standard, the said cam being held in a normal elevated position by a spring 22, but on rotation of the cam the plunger 19 will be depressed.

This plunger is adapted to be normally held in an elevated position and is provided with a collar 23 above which a spring 2 1- is located, the said spring engaging at its upper end with the washer 25 on the plunger and located below the deck of the car.

0n the lower end of the plunger 19 a vertical roller 26 is rotatably mounted and below this roller a wheel 27 is journaled. When a car or train equipped with this mechanism is approaching a switch the driver or motorman may rotate the cam 21 by hand to depress the plunger 19 to the desired extent so that the vertical roller 26 will engage with the star wheel 14 and rotate the same so actuating the crank shaft 10 and throwing the switch in the desired direction.

By providing the roller 26 excessive friction on the plunger 19 is eliminated while the wheel 27 will make rolling contact with the ground should the plunger 011 depression engage the .same and the use of the wheel 27 will thus prevent any sudden force being exerted on the plunger which would tend to bend the same.

In the event of the motormans or drivers hands being occupied at the precise moment at which the switch is to be thrown, he may actuate the plunger by placing his foot on the pedal 20, thus leaving his hands free.

After the pressure has been released from the foot pedal 20, the plunger 19 is returned to its normal position under the action of the spring 2%. If the plunger 19 has been actuated by the cam 21, the saidcam on being released will be returned to its nor-malallowing the position by the spring 22, plunger19 to 'be returnedto its normal 'posi tion by the spring 24.

From this descriptionit will beseenthat I have invented a switch actuating mechanism which can be-advantageously-used on street and railway cars, so that-the switch may be'thrown when a'car or train is ap- ,proaching thesame,-the said-mechanism be- .ing capable of being actuated 'by-foot or hand, ina manner to suit the convenience of the operator.

" 'Asmany changes could be'inade inthe fabove description and many apparently Widely 'difierent embodiments of my inven- 'tion' Within the" scope of the claims construeted without departing from the-spirit or scope thereofl it is intended that all matter contained in the accompanying specification anddrawings shall be interpreted as illustrative and not in a limited sense.

- Gopis of this patent may be obtained standard, a plunger slidably mounted in the I standard, a roller on the lower end of the plunger, a wheel below the roller, resilient means for returning the plunger to a normal position, a foot pedal on the plunger, and a manually operated cam on the stand- 'ard co-acting with thehead of the plunger.

2. A switclnng device of the class (loscribed"including track means, our means "consisting of'a standard, a plunger slidahly mounted in the'standard, a roller on the lower end of the plunger, 'foot means for actuating the plunger, a hand controlled cam on the top of the standard (to-acting with'the top of the plunger,"and resilient I means for holding the cam to normally permit of the plunger beingheld in an elevated position.

' In Witness whereof I have hereunto set my 'MORRIS WINNING.
